Thanks badly worded question my fault, i am looking to stop by size, so any file over say 1mb will get refused. I know you can set limits on sizes of page viewed so think it may be possible to do the same for files (persistence policy object)

1. set up a seperate volume on your Hard Disk for downloads only.
2. then set up a disk quota for the volume
3. also set the default download path for Internet Explorer to point to the newly created volume
4. then set the GPO to not allow changes to the browser or connection settings
